generic_permission(9)
NAME
generic_permission - check for access rights on a Posix-like filesystem
SYNOPSIS
int generic_permission(struct inode * inode, int mask,
int (*check_acl) (struct inode *inode, int mask));
ARGUMENTS
- inode
- inode to check access rights for
- mask
- right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)
- check_acl
- optional callback to check for Posix ACLs
DESCRIPTION
Used to check for read/write/execute permissions on a file. We use
"fsuid" for this, letting us set arbitrary permissions for filesystem
access without changing the "normal" uids which are used for other
things..
